Processing of Nickel Laterite Ores on the Rise

Sulfide Ores. Sulphide ores were mostly created by (i) the intrusion of molten magma from the mantle into the crust of the earth and (ii) the formation of localized metal-rich sulphide ore bodies by sequential solidification and/or hydrothermal leaching and precipitation. From: Extractive Metallurgy of Nickel, Cobalt and Platinum Group Metals, 2011

Copper Nickel Flotation

The Bureau of Mines investigated the flotation responses of two copper nickel ore samples from the Duluth Complex with the objective of recovering bulk sulfide concentrates. One of the ores studied was taken from a test pit; the other was taken from a test shaft. The samples were quite similar except that the pit sample analyzed 0.35 pct Cu and 0.11 pct Ni and the shaft sample analyzed 0.69 .

This is different from the sulphide ores as the nickel occurs in a discrete mineral. The limonitic ores are processed using acid leaching (hydrometallurgical), the saprolite ores are smelted (pyrometallurgical) and a limonite-saprolite blend can be extracted using the Caron process (pyro/hydrometallurgical).
